Ruptured AAA remains a particularly hazardous condition to treat. There are a number of advantages of EVAR in this condition. A number of the problems early in the experience of EVAR have been addressed, but further experience is required to demonstrate its efficacy when compared with open repair.

neck angulation was the risk factor most significantly related to PPE and graft migration.

We have not demonstrated any evidence for proximal neck dilatation after endovascular repair of abdominal aortic aneurysm.

The results suggest that the degree of bowel ischemia, endotoxemia, and cytokine generation following elective infrarenal AAA reconstruction may be reduced if the endovascular technique is used instead of conventional surgery.

IAAA may be successfully excluded by the endovascular technique, and EVAR is particularly useful where open repair has failed. The impact of endograft placement on perianeurysmal fibrosis is less clear. In this study, there was no suggestion that the degree of PAF worsens following endovascular repair.
